I don't get the mind flayer either. why not use a creature that cost nothing? like a spark? with your sopa down the sparks, that cost nothing will not die and just get bigger. then when you fractal them you can play down as much as you can, because of the zero cost. or you could use aflatoxin so you mcells can grow and grow! then again those ideas have been used before so if you want something creative don't use these.
